Description Arshavir Grigorian 2005-06-08 15:05:02 UTC

We have a large logical volume (6.91T) which contains a JFS. All of a sudden we
were unable to mount the volume:

mount /mnt/san
mount: wrong fs type, bad option, bad superblock on /dev/vg00/lvol0,
       or too many mounted file systems

We then tried to run fsck.jfs and got a Segmentation fault. 

lvdisplay and vgdisplay seem to work fine displaying the correct info.

Comment 1 Arshavir Grigorian 2005-06-08 15:46:54 UTC

Additional info:

Linux nutcracker 2.6.12-rc6 #1 SMP Wed Jun 8 16:46:17 EDT 2005 x86_64 AMD
Opteron(tm) Processor 244 AuthenticAMD GNU/Linux

That's the only kernel version (2.6.12) that has support for a fiber channel
Emulex card (lpfc).

This bug was reported to the jfs-discussion mailing list, and found to still be
a problem with jfsutils-1.1.8.  Running fsck.jfs --omit_journal_replay "fixed"
the problem.

I don't have x86_64 hardware, so I'd be interested in investigating this some
more if you see it again.
